answers 402

Read on-chain state of a Uniswap V3 pool: token0/token1 addresses + decimals, fee tier, current sqrtPriceX96, tick, in-range liquidity, and the decoded human-readable spot price (token1 per token0). One $0.002 call replaces ~6 RPC roundtrips on the caller's side.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
